Take a look at the Cadbury video from Fallon London. A really nice, clean, and simple idea. Kids playing a song with their eyebrows (and a bit with a balloon). Great casting choices, simple art direction, and a good choice of song. The page where I got it has nothing but positive comments on it about this spot.
But I'm sorry.
Without even a thin thread of logic tying back to the product, you don't got shit. The creatives for this spot should be in a different industry. This isn't something that will sell the client's product. And if it doesn't sell the client's product, then you're just wasting their money and their time on a personal art project. And that is advertising malpractice. You should be sued.
